Question

A) ax+2a B) 10a+20ab C) x²-100 D) 4m-3mx E) 1+2y+y² F) x²-10x+25 G) xy+y²-y H) 14x-21x²y+35xy I) a²-4ab+4b2 ME AJUDEM PFV!!!

Answer 1

a) ax +2a = a (x + 2)

b) 10a + 2ab = 10a (1 + 2b)

c) x² - 100 = x² - 10² = (x - 10)(x+ 10)

d) 4m - 3mx = m (4 - 3x)

e) 1 + 2y + y² = (1 + y)² = (1 + y)(1 + y)

f) x² - 10x + 25 = (x - 5)² = (x - 5)(x - 5)

g) xy + y² - y = y(x + y - 1)

h) 14x - 21x²y + 35xy = 7x (2 - 3xy + 5y)

i) a² - 4ab + 4b² = (a - 2b)² = (a - 2b)(a - 2b)

Espero ter ajudado! Bons estudos!
